M11 NS2 CQB Project

Im not sure about everywhere else, but up here in Washington, our CQB facilities run a strict 300 FPS limit on all guns, 300 being the advised and 330 being the absolute max. I figure without a TBB, the only application this gun has is CQB, and since i have always wanted an M11, i feel now is the time to start this, especially with the NS2 version being so well updated over the last one.

The problem:
NS2 shoots too hot for CQB
Stock does not have enough accuracy for field
Need a CQB gun that is small but doesnt look awkward, every AEG option ruled out for either being too much of a hassle or too expensive (case in point a P90 or AKS-74u, P90 too expensive, AK too complex, i hate V3 gearboxes), M4 stubbies look stupid, and i love the M11.
Need a small gun that i could use for field in certain situations

Solution:
KWA NS2 M11A1
RA-Tech NPAS
EDGI TBB

I figure i can browse the internet for cheap mags, but i would love to get the M11 new, even if it means i have to spend a bit more.

What i could use some help on is the barrel assembly and getting to the gas block. I know how to install the NPAS and everything, but unsure how to disassemble the M11, i guess this is going to be needed to clean and lube the gun as well. The barrel assembly is something i havent ever touched on a KWA/KSC gun, and im unsure how to take it apart to install the tightbore barrel, is there a guide to installing one around? I havent found one as of yet.

Any and all help is greatly appreciated.

The edgi tightbore is only going to increase your fps.

What I recommend is to ask around to see if you could use hfc134a gas in the m11a1 ns2. that should reduce your fps to 300 or below if it works

This is true but what he is saying is that he would use the NPAS system to reduce the fps after the tbb is installed, therefore allowing him to keep the accuracy boost but drop the fps. Now the question is how low the NPAS allows the M11A1 with the tbb fps increase to shoot. If it allows him to get all the way down to 300 fps then problem solved (although the quality of the npas system doesn't seem all that great from what I have read).

Duster gas was able to drop the FPS below 330 FPS into the limit for my CQB field, however gas efficiency was not as good as with propane and the ROF took a slight decrease. I bought the newest version of NPAS and it is of superior quality to the first version. Adjusting is a bit of a pain in the gun but the FPS can be adjusted all the way from the stock 350 range down to 0, thats right, 0 FPS, the gun will fire but gas will not launch the bb.

Unfortunately i have to postpone the TBB as i need a G&P Steel kit, one of my idiotic friends wouldnt listen to me and repeatedly pulled back the stock without unfolding it, it was like a retarded dog running into a wall over and over expecting a different result each time.

Nonetheless, this was going to be installed anyway, i just have to bump it up now....

In conclusion, the NPAS fits and works perfectly in the M11, this allows the gun to be used at any and all fields and CQB arenas without a drop in performance, the only thing that the NPAS changes is the FPS so that blisteringly fast ROF is unchanged.

Nice glad to hear the NPAS fits and works perfectly. G&P Steel Kit, NPAS kit, and eventually a TBB, sounds like you'll be having one nice m11.
